-D Air Sampler
The Partisol 2000
i
can be configured to operate with a variety of inlet
systems depending on the type of sampling being performed. For most
configurations, a standard PM
10
inlet is used, operating at a flow rate of 16.7
L/min (1 m
3
/hr) to provide the initial D
50
particle size cutoff. For PM
10
sampling, a straight downtube with adapter is installed inside the enclosure.
For PM
2.5
sampling, the U.S. EPA requires the use of VSCC or WINS
Impactor after the PM
10
inlet and this device is installed inside the enclosure.
Additional size sampling may be accomplished through the use of a TSP
(total suspended particulate matter) inlet or a PM
1
cyclone.
The Partisol 2000
i
-D uses a PM
10
inlet operating at 16.7 L/min (1 m
3
/h) to
provide the initial D
50
particle size cutoff at a 10 micron diameter. The virtual
impactor, or
“dichotomous splitter,” is located after the inlet, and two
separate flow controllers
maintain the fine particle stream at 15.0 L/min and
the coarse particle stream at 1.67 L/min.
